HEEL-FOR SHOES Filed May 15. 1930 INVENTOR HENR YBDUVfiEN ATTORNEY Patented Sept. 15, 1931 UNITED STATES HENBY IB. DUYSEN, OF ELYIBIIA, OHIO HEEL FOR SHOES Application filed May 15,.1930. Serial No. 452,614.

This invention relates in general to shoes and more particularly to mud guards for shoes andhas for its principal object an improved combined heel and mud guard which will be highly efficient in preventing the upward throwing of mud, wet dirt and slush onto the pantaloons or skirts or hose during walking proceedings, and which will be economical in manufacture.

A further object of the invention is to provide a combined heel and mud guard with a guarding wall embracing the rear end of the heel, which guarding wall is formed with vertically arranged recesses to more readily permit reformation of said wall and to enable instantaneous automatic release of any dirt or snow caught between said guard wall and the rear wall of the heel.

Still'further objects of the invention will more readily be understood from the following description of the preferred form of construction as illustrated in the accompanying drawings, in which Fig. 1 is a side view of an Oxford showing the combined heel and mud guard. Fig. 2 is an enlarged bottom view partly in section of the combined heel and mud .guard shown in Fig. 1. Fig. 3 is a sectional view on line 33 of Fig. 2. Fig. 4 is a side view partly in section of a zipper with the combined heel and mud guard and Fig. 5 is a diagrammatic view showing the relationship of the guard wall to the rear edge of the heel proper.

Referring to the drawings, the rubber heel 2 includes the customary bottom 3 with circular openings 4 to attach heel 2 to the oxford or shoe 5. Rear portion 6 of bottom 3 is recessed on crescent curves 7 and 8 intersecting each other at 9 and the so-formed recess 10 is of general V-shaped cross section with decreasin depth toward the intersections 9 of curves and 8. The V-shaped recess 10 is preferably so arranged that wall 11 at the outer edge of heel 2 is of approximately uniform thickness, which wall, extending downwardly from heel body 2, terminates'at itsv rear edge above the bottom of heel body 2 and approaches bottom 2 on inclined lines approximately opposite intersections 9 of crescent curves 7 and 8. It can readily be seen that the rear edge of the supporting surface of bottom 2 is formed by crescent curve 8 and that the lower edge 12 of wall 11 is generally untouched during walking proceedings except in slush or muddy weather. Wall 11 therefore will readily act to catch any particles of mud and water or dirt and direct the same downwardly, thus preventing splashing or throwing of mud and water upon the shoe or stocking of the wearer.

In sleety or muddy weather recess 10 might fill w1th dirt or slush and prevent proper action of guard wall 11. To avoid such act on wall 11 is thinned out at symmetrical lines 14 perpendicular to the walking surface 3 of the heel, and forms strictly defined bendmg or link areas more readily permitting sprlnging of wall 11 during walking proceedings in dirt or slush. It is to be understood that when slush or mud covers the ound lower edge 12 of wall 11 contacts with the ground rior to walking surface 3 and readily yiel s and thereby changes its form approximately as shown in dotted lines in Fig. 2 until the walking surface 3 contacts with the ground. The amount of slush gathered in recess 10 is substantially less therefore than the actual size of recess 10 so that the heel when lifted and after springing of wall 11 to its original form will readily release any slush gathered in recess 10 while wall 11 is'again in proper working position to guard against splashing.

It has been found that the proportions as given in diagram Fig. 5 are especially adapted to achieve the results described. Thus the thickness (a) of wall 11 should be approximately of an inch and the edge thereof at the rear end of the heel is about of an inch above the ground. Such heights also depend upon the distance 0 between the rear edgeof walking surface and wall 11 and is further governed by the angle A which should not be longer than approximately 25-35.

While I prefer the dimensions given, I do not wish to limit myself to such dimensions, same being merely given as general lItlfitlllctloIls to achieve most satisfactory res ts.

What I claim, is:

A combined heel and mud-guard comprising a rubber heel having a walking surface and a guard wall spaced :1 art from and encircling the rear edge of sand heel, said guard wall including recessed portions vertically arranged with respect to said surface to induce deformation of said wall on predetermined lines, the rear edge ofsaid wall terminating above said walking surface and approaching said surface on inclined lines.

In testunony whereof I alfix my si ature.
